After upgrading to IE9, some users reported the Nefsis menus appeared in a vertical view instead of the regular tiled view. This anomaly is caused by IE's Compatibility View feature.

To fix the issue you have to disable the Compatibility View option when visiting the Nefsis.com website. The Compatibility View option is located in IE's Tools menu and it can be toggled on or off. If the Tools menu is not visible in IE, simply click the button on your keyboard and that will display IE's Menu bar.
